Sierra 1310 Varminter 22 Cal 45gr Spitzer Bullets 100/Box

The Sierra 1310 Varminter delivers exceptional accuracy and devastating terminal performance for small game and varmint hunting. These precision-manufactured 22 caliber bullets feature Sierra's proven spitzer design that maximizes ballistic coefficient while maintaining consistent expansion at impact velocities.

What Makes This Different

Sierra's Varminter line incorporates a thin jacket construction specifically engineered for rapid expansion on contact with soft targets. The 45-grain weight provides an optimal balance between velocity retention and knockdown power, outperforming lighter bullets that shed energy quickly. Each bullet undergoes Sierra's rigorous quality control process, ensuring weight consistency within +/- 0.3 grains and concentricity tolerances that exceed industry standards.

Key Features

• 45-grain spitzer design optimizes ballistic coefficient for flat trajectory
• Thin jacket construction ensures rapid expansion on varmint-sized targets
• Precision-drawn copper jacket maintains structural integrity during flight
• Lead core composition provides consistent weight distribution
• Boat-tail base design reduces drag and improves long-range accuracy
• Compatible with standard 22 caliber rifle cartridges (.223 Rem, .22-250, etc.)
• 100-count packaging reduces per-round cost for high-volume shooters

Field testing demonstrates consistent sub-MOA accuracy when loaded with appropriate powder charges and seated to proper depth. The 45-grain weight excels in medium-capacity cartridges like .223 Remington and .22-250, delivering muzzle velocities between 3,200-3,800 fps depending on barrel length and load data. Wind deflection remains minimal out to 300 yards, making these bullets effective for prairie dog colonies and similar long-range varmint scenarios.
